C# Problem with Receiving data

When I send data from the client side many times one after another very quickly, i don't receive these data separately in the server. I receive them as one large data burst. I need send the reply for every received data . But i can't do it, because these data join in one large burst. How can I send reply for every received data? Here the code of callback method in the server:

    private void RecieveCallback(IAsyncResult asyncResult)
    {
        ConnectionInfo connection = (ConnectionInfo)asyncResult.AsyncState;
        try
        {
            int bytesRead = connection.Socket.EndReceive(asyncResult);

            if (bytesRead > 0)
            {
                for (int i = 0; i < bytesRead; i++)
                    connection.FullBufferReceive.Add(connection.BufferReceive[i]);
                if (bytesRead == connection.BufferReceive.Length)
                {
                    connection.Socket.BeginReceive(connection.BufferReceive, 0, connection.BufferReceive.Length, 0,
                                                   new AsyncCallback(RecieveCallback), connection);
                    Console.WriteLine("Bytes recieved -- " + bytesRead + " by " + connection.Id);
                }
                else
                {
                    Console.WriteLine("Bytes recieved " + bytesRead + " by " + connection.Id);

                    _serverController.StartProcess(connection);
                }
            }
            else  
                CloseConnection(connection);
        }
        catch (Exception e)
        {
            CloseConnection(connection);
            Console.WriteLine(e.ToString());
        }
    }

If your sockets are TCP (I can't tell from the code), this is expected behavior as TCP isn't framed like UDP is. You need to delimit the data yourself.
